Javascript Question

Im a newbie at JS but i have tried to create an if statement on my calculator, that when the result of a multiplication or addition etc is bigger than 20 an alert comes up. The calculator works fine but not the the if statement.

**JS:**

`var a,b;`

function setValues()

{

a = Number(document.getElementById("a").value);

b = Number(document.getElementById("b").value);

}

function sum()

{

setValues();

result = a+b;

alert("the sum is equal to "+result);

}

function rest()

{

setValues();

result = a-b;

alert("the rest is equal to "+result);

}

function mult()

{

setValues();

result = a*b;

alert("the operation is equal to "+result);

}

function div()

{

setValues();

result = a/b;

alert("the operation is equal to "+result);

}

if (result > 20) {

alert("heyy thats pretty big");

}

Answer Source

Your `if`

statement should be inside each operator function like so:

```
function div()
{
setValues();
result = a/b;
alert("the operation is equal to "+result);
checkResult(result);
}
function checkResult(result){
if(result > 20)
alert("heyy thats pretty big");
}
```
